I ran across this thing the other day. Would it be helpful to anyone on HF?
Looks like a nice xen VM box. But, just about any 2nd hand laptop with an SSD will work well if you want to home dedicate hardware toward your personal domain. The real issue for domain hosting of large content or high avatar load is bandwidth and for that I believe it is better to host a domain at a commercial site.
For the vast majority of current HF users (all 60 of us), hosting locally seems more than good enough for now
